Description

Disc centrifuge with discharge rotatable centripetal pump

Technical Field

The utility model belongs to the technical field of disk centrifuge, concretely relates to disk centrifuge of rotatable centripetal pump of area ejection of compact.

Background

The disk centrifuge can separate solid, liquid and liquid continuously, and is one kind of vertical centrifuge. A small gap is left between the disks. The suspension (or emulsion) is fed into the drum through a feed pipe located in the center of the drum. As the suspension (or emulsion) flows through the gaps between the discs, the solid particles (or droplets) settle by the centrifuge onto the discs to form a sediment (or liquid layer). The sediment slides along the surface of the disc to be separated from the disc and is accumulated at the part with the largest inner diameter of the rotary drum, and the separated liquid is discharged out of the rotary drum from the liquid outlet. The disc is used for shortening the settling distance of solid particles (or liquid drops) and expanding the settling area of the rotary drum, and the production capacity of the separator is greatly improved due to the disc arranged in the rotary drum. The solids accumulated in the drum are removed manually by disassembling the drum after the separator is shut down, or discharged from the drum through a slag discharge mechanism without shutting down the separator.

Centripetal pumps are also known as energy cutting rings. Is a pressure pump used for collecting liquid and discharging liquid above in a butterfly-plate centrifuge (comprising a vertical Bo Pailiao sedimentation centrifuge and an extractor). The centrifugal pump has the same action principle as that of a centrifugal pump, and the fixed impeller and the rotating clarified liquid phase separated by the centrifugal machine act to convert the kinetic energy of the liquid into static pressure energy for pressure discharge.

At present, when the mixed liquid is separated by a disk centrifuge, the mixed liquid enters the inside of a rotary drum body from a feeding pipe in an axial speed mode, and finally enters the inner space of a disk to be separated through the flow guiding effect of the wall surface of the rotary drum body, heavy phase is thrown to the outer edge of the rotary drum body under the action of centrifugal force, however, circumferential acceleration is not performed when the mixed liquid is input into the rotary drum body, the rotary drum disk rotates at a high rotating speed, the difference between the two causes that the fluid is greatly sheared, liquid drops are easy to break and emulsify, local instability is increased, a stable interface in a flow channel is damaged, and the separation efficiency is finally reduced.
